EFX to DWG Conversion: FAQ

What are EFX files?

EFX (eFax) is a proprietary file format used by eFax for storing fax documents in digital form. EFX files typically contain fax images, text, and related document data and are commonly created when receiving or saving faxes through eFax services. The format is primarily intended for viewing and managing fax documents within compatible eFax software. Because EFX files are not widely supported by standard image and document applications, conversion to more common formats such as PDF, TIFF, or JPEG can be useful for archiving, sharing, and further processing.

What are DWG files?

DWG (which stands for "Drawing") is a proprietary format of AutoCAD, a program widely used for creating engineering and architectural projects. The format is also a default extension used by several other computer-aided design (CAD) pieces of software, including IntelliCAD, Caddie or DraftSight. DWG files contain complex design structures including several layers, which can be 2-dimensional or 3-dimensional.
